Caring for a cactus may seem effortless—after all, it’s a desert plant, right?

At Succulux.be, we understand the nuances of plant care in the Low Countries. Whether you’re a hobbyist or a plant collector, this article will help you master the art of watering your mini cacti and succulents.
Understanding Your Mini Cactus and Local Climate
Why climate matters in cactus watering
Belgium and the Netherlands have moderate temperatures with relatively high humidity. Unlike arid desert climates, these conditions slow water evaporation, making cactus care more delicate. What thrives in Arizona may rot in Antwerp if not properly adjusted.
Indoor vs outdoor placement
-
Indoor cacti need less water due to limited sunlight and lower evaporation.
-
Outdoor cacti, particularly in spring and summer, may require slightly more attention—but always check the soil.
How Often to Water Cactus Indoors
General indoor watering frequency
For indoor environments across Flanders, Brussels, and Dutch cities like Amsterdam or Rotterdam:
-
Spring & Summer: Every 2 to 3 weeks
-
Autumn: Once a month
-
Winter: Once every 5–6 weeks, or not at all
This schedule depends heavily on soil dryness. Always check if the top 3–4 cm of soil is bone dry before watering.
Best indoor cactus watering practices
-
Use room-temperature water.
-
Water deeply until it drains from the pot’s bottom.
-
Never let the cactus sit in water.
How Often to Water Cactus Outdoors
Cactus watering in patios and gardens
Outdoor mini cacti placed in sheltered areas can flourish in our northern European climate, especially during the warmer months.
-
Spring: Every 10–14 days
-
Summer: Every 7–10 days during dry spells
-
Autumn: Every 3–4 weeks
-
Winter: Usually no watering required
Avoid watering during or before freezing temperatures.
Signs Your Cactus Needs Water
Knowing when to water isn’t just about a calendar.
Visual cues that indicate a thirsty cactus:
-
Wrinkled or shriveled stems
-
Pale color
-
Loss of firmness (soft to touch)
Signs you’ve overwatered:
-
Mushy base
-
Yellowing
-
Black spots or mold

Using the Right Soil for Belgian Climate

50% cactus potting soil

25% coarse sand

25% perlite or pumice
Avoid garden soil or peat-based composts which retain too much moisture.

FAQ: How Often to Water Cactus
How often should I water my cactus in winter in Belgium?
Once every 5–6 weeks or not at all. Only water if the soil is bone dry and the plant shows signs of dehydration.
Can I use tap water to water my cactus?
Yes, but let it sit for 24 hours to release chlorine. Rainwater is ideal if collected safely.
Why is my cactus turning yellow?
Overwatering is the most common reason. Check the roots and soil moisture before watering again.
Is misting a good idea for cactus?
No, misting can cause mold and doesn’t penetrate to the roots. Always water directly into the soil.
Should I water more in summer?
Slightly more, yes. Every 7–10 days is ideal during heatwaves. But always confirm soil dryness before watering.
Can I grow cactus in the bathroom?
Bathrooms are often too humid for most cacti. Better to place them in dry, sunny spots.
What is the best soil for cactus in Belgium?
A mix of cactus soil, sand, and perlite works best. Avoid water-retentive soils common in garden centers.
